A young Princess Elizabeth marries Prince Philip. As King George VI’s health worsens, Winston Churchill is elected prime minister for the second time.

With King George too ill to travel, Elizabeth and Philip embark on a four-continent Commonwealth tour. Party leaders attempt to undermine Churchill.

Inspired by Jackie Kennedy and against her government's wishes, Elizabeth takes an unconventional approach to resolving an issue with Ghana.

Philip insists that Prince Charles attend his alma mater in Scotland and reminisces about the life-changing difficulties he experienced there.

The Queen gives Charles the green light to wed Camilla. Tasked with planning her own funeral ahead of her 80th birthday, she faces an existential crisis.
